The photon model of light

Webb9 sep. 2024 · According to the theory of relativity, the momentum of a beam of light is given by p = E / c. Apply this to find the momentum of a single photon in terms of its frequency, and in terms of its wavelength. Combining the equations p = E / c and E = hf, we find p = E / c = h cf. To reexpress this in terms of wavelength, we use c = fλ: WebbPhotoelectric effect. Tools. The emission of electrons from a metal plate caused by light quanta – photons. The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and ...
